How to Watch Hillary Clinton, Donald Trump Face Off in First Presidential Debate

The debate starts at 6 p.m. PT tonight.

Television news media are expecting Monday night's first presidential debate between Hillary Clinton and Donald Trump to be a yuuuge ratings night, with some observers guessing that more than 100 million people could tune into the face-off.

The debate, which airs commercial-free for 90 minutes tonight at 6 p.m. PT, will air live on every major broadcast network — ABC, CBS, Fox, NBC — as well as cable news channels including CNN, Fox News, CNBC and MSNBC. Univision is also airing the debate.

But those predictions aren't factoring in just how easy it will be to find the debate live online. Every major streaming outlet, from YouTube to Twitter, will make it easy to watch the showdown from a computer screen or Apple TV. THR lays out the many options in this handy guide:
